title: [GABA fluophore formation due to ninhydrin reaction in the octanolic milieu. Spectrofluorometric investigation. 2nd information (author's transl)].
abstract: As a result of the reaction of ninhydrin with gamma-aminobutyric acid and glutamic acid in the octanolic milieu, a fluorescent product, presumably a copper-II-chelate-complex, was formed. Partial reaction steps were investigated spectrofluorometrically. The excitation and emmission spectra resulting from the reaction between ninhydrin and glutamic acid, ninhydrin and gamma-aminobutyric acid, and ninhydrin, glutamic acid and gamma-aminobutyric acid were measured. Possible consequences are discussed with respect to fluorescence histochemical procedures.
